I always get frustrated with climate discussions, because there are two very important things that I never see discussed:
Radiative heat loss is proportional to temperature to the 4th power.
CO2 concentration is the rate limiter for photosynthesis because Rubisco is a dumb protein. This means that doubling the concentration of CO2 approximately doubles the rate of photosynthesis.
These two things mean that it's pretty much impossible to have runaway greenhouse gas effects from CO2. There may be some local effects and ocean acidification (where iron concentration ends up being the photosynthetic rate limiter), but the planet isn't going to explode because we burn fossil fuels.
And no, methane release isn't an issue either because it only has an atmospheric half life of 9.1 years.
